SharePoint 2010 'Telerik.Web.UI' could not be loaded.

[Brad]

Hi -

I have:
Installed AJAX
Installed RadControls_for_ASP.NET_AJAX_2010_1_519_dev.msi
Added a RadGrid to a web part
Complied and deployed using VS 2010

On runtime I get:

Parser Error

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: Could not load file or assembly 'Telerik.Web.UI' or one of its dependencies. The system cannot find the file specified.

Assembly Load Trace: The following information can be helpful to determine why the assembly 'Telerik.Web.UI' could not be loaded.

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

One issue may be that I do not see two required dll's in the GAC.

Telerik.Ajax.SharePoint.dll and RadEditorSharePoint.dll.

I do not see these anywhere in the Rad install path or on my hard drive either.

Please advise where these are located.

I noticed when I ran the Telerik installer it did not update the GAC or sp web.config either.

Thank you.

Hello Brad,

It seems that you are using an older unofficial version of our Telerik AJAX controls for SharePoint 2010 installation. The first official version of our SharePoint 2010 Ajax installer is announced with the Q2 2010 release of the suite.

Can you please switch to the latest release of our SharePoint 2010 AJAX web parts (available for download under your account, with Telerik.Web.UI version number 2010.2.826) to see whether this helps? Let us know how it goes.

Kind regards,
Sebastian
the Telerik team

I download that and try again.

Thanks for the quick reply.

Hi -

I am still getting an error using a newer package.  Please advise on what I can do.  I cannot get the RadGrid to load in my Visual Web Part in SharePoint 2010.

Hello Brad,

In case you used the automatic SharePoint 2010 msi installer it should automatically add proper references to the Telerik.Web.UI assembly in your SharePoint 2010 sites. To register the assembly manually, follow the instructions from this help topic. This should help you eliminate the exception.

I don't mean to hijack this thread, but where do you get the msi installer for SharePoint 2010? I am evaluating now and do not see it.

Regards,

Sean

[Sebastian]

Hello Sean,

The SharePoint 2010 AJAX installer is located in the RadControls for ASP.NET AJAX product files download as illustrated in the screenshot from this KB article.

Best regards,
Sebastian
the Telerik team

[Sean]

I got to the second step in the KB, but unfortunately there is no "Browse All Product Files" at that location. Is that because I have the trial version?

[Sebastian]

Hello Sean,

This might be the case if you downloaded a free trial of the entire Ultimate Collection zip package. In this case the Telerik AJAX SharePoint installer should be part of the zip file. Otherwise you should be able to browse all product files by navigating from the 'RadControls for ASP.NET AJAX' section on this page.

Kind regards,
Sebastian
